Oh, plenty:

- beware fake holiday decorations (lights, extension cords)

- Keep candles away from children, pets and combustible materials, always making sure to blow them out before leaving the room or going to sleep.

- Don't overload extension cords.

- Don't string together too many Christmas lights (electrical overload > overheat > fire)

- Stay in the kitchen while cooking, as unattended cooking is the leading cause of kitchen fires.

- Keep a close eye on anyone cooking or smoking while under the influence of alcohol.

- Ensure that there is at least 3 feet of clearance for all space heaters.

Otherwise have a happy holiday!
